Embodiment 1

[0023] Embodiment one: a kind of four-quadrant elevator control system, such as figure 1 As shown, it includes a control center 1, which is used to receive the data transmitted by the sensor module and control the operation of the AC motor 2. The control center 1 includes an identification module, a processing module and a storage module. The storage module stores user identity information and is connected to the identification module. , the input end of the identity recognition module is connected to the sensor module, the output end of the identity recognition module is connected to the input end of the processing module, and the output end of the processing module is connected to the AC motor 2; for the four-quadrant module, the current input end is connected to the three-phase power supply 16, and the current output The four-quadrant module includes a rectifier module 18 and an inverter module 23. Both the rectifier module 18 and the inverter module 23 include 3 sets of par...

Embodiment 2

[0028] Embodiment two, such as Figure 4 As shown, a four-quadrant elevator control method is suitable for a four-quadrant elevator control system, including the following steps: Step s1: When someone approaches the elevator door from the first floor, the camera takes pictures of the approaching person and identifies the approaching person Personnel identity; step s2: if the person approaching is a resident, obtain the location of the elevator and the floor where the person approaches. When the sensor is located above the floor and the elevator has reached the first floor, the elevator door and the 7 doors of the bridge compartment are opened. After the infrared sensor detects that a person approaching enters the elevator, the elevator goes directly up to the floor where the person lives; step s3: if the person approaching is When not a resident, it is judged whether there is image information of the approaching person sent by the resident through the wireless communication mo...

Abstract

The invention discloses a four-quadrant elevator control system and method. The system comprises a control center, a four-quadrant module, an alternating current motor, a sensor module, a cab system and a three-phase power source. The control center is used for receiving data transmitted by the sensor module and controlling operation of the alternating current motor; a current input end of the four-quadrant module is connected with the three-phase power source, and a current output end of the four-quadrant module is connected with the alternating current motor; the alternating current motor isinstalled on the top of a well, a current input end of the alternating current motor is connected with the four-quadrant module, and a control end of the alternating current motor is connected with the control center; the sensor module is used for detecting the identify of a person taking an elevator and connected with the control center; the cab system is connected with the alternating current motor and used for carrying residents; and the three-phase power source is used for supplying power to the alternating current motor after passing through the four-quadrant module and connected with the four-quadrant module. According to the four-quadrant elevator control system and method, non-residents are prevented from using the elevator, the safety guarantee for the residents is enhanced, unessential elevator operation is reduced, the energy is saved, the situation that the person is clamped by an elevator door is avoided, and the safety is improved.

Description

technical field [0001] The invention relates to the technical field of elevator control, in particular to a four-quadrant elevator control system and method. Background technique [0002] At present, with the development of society and the improvement of economic level, people no longer pursue food and clothing, but begin to pursue the quality of living standards. At the same time, they also pay more and more attention to property and personal safety. Most high-end residential areas have one household per floor, which satisfies the quality of life of residents and better protects the safety of residents' lives and property. However, despite the presence of guards in the residential area, there are still cases of strangers entering the residential buildings, stealing and even threatening the safety of residents' lives. The reason is that the stranger can take the elevator to the resident floor at will after understanding the basic situation of the residents. [0003] Traditi...
